Sonic Turbo Wash Bearing Cleaner SystemThe Sonic Turbo Wash Bearing Cleaner System is basically a laundry machine for your skate bearings! This system makes bearings shine for a faster, smoother roll on any surface. Not only does this maintenance prolong the life of your bearings, it also helps them spin like new. Your bearings stay suspended in the strainer tub, while the dirt sinks to the bottom. Once you're done, you can use the Sonic Super Oil to lubricate your bearings if needed.
